7 Claims.

'I'his invention relates to a new and improved ball bearing washingmachine.

In the manufacture of bearings and particularly ball bearings, thetolerances of the inner and outer races and of the intermediate ballsare very critical. Further, the nish or polish on the rubbing surfacesis a very important factor in the success or failure of any ballbearing. It is therefore foreseeable that particles of metal or dirtbecoming accidentally deposited on these finished surfaces will causeabrasion and scratching which will alter the desired bearing operationas well as in certain instances destroy the very critical tolerancesmaintained during the manufacture of the bearing. It is therefore veryimportant to thoroughly wash the bearings after manufacture and beforeuse.

A principal object of this invention is to provide a machine for washingball bearings for the purpose of removing all foreign particles from thebearing surfaces thereof.

An important object of this invention is the provision of means in aball bearing washing machine for adjusting the machine to accommodatevarious sizes of bearings.

Another important object of this invention is to supply an adjustableball bearing washing machine capable of washing any size bearing andmeans associated with the adjustment for bearing size to automaticallyvary the size and quantity of the impinging stream of washing liquid.

A further important object of this invention is to provide means forlaterally feeding a single bearing from the bottom of a vertical stackof bearings.

Another and further important object of this invention is the provisionof a ball bearing washing device in which streams of washing liquid aredirected at the bearing from opposite sides and at an incline andarranged in such a, manner that the inner race rotates with respect tothe outer stationary race during washing thereof.

Other and further important objects of this invention will becomeapparent from the disclosures in the following specification andaccompanying drawings, in which:

Figure 7 is a sectional view taken on the line 'i-'I of Figure 6.

Figure 8 is a detail of a portion of the device as viewed from line 8 8of Fig. 6.

As shown in the drawings:

The reference numeral I indicates generally a supporting structure orframework on and in which is mounted a bearing washing machine I I. Awash fluid such as a very thin lubricating cil is applied under pressureto the conduit I2. whereupon it is circulated through the washingmachine and is delivered by means of conduits I3, I and I to fittings orthe like I6, I'I and I8 respectively.

A bearing magazine I9 is adapted to receive and maintain a substantiallyvertical Stack of bearings 20. A feeding mechanism 2I is adapted toslide the bottom bearing of the Vertical stack therefrom withoutupsetting the other bearings in the stack and pushing it longitudinallyinto the washing machine II. As shown in Figure l, the hearings 22within the washing machine are in continuous end-to-end relationship andas they are advanced by the insertion of succeeding bearings from thestack 28 they are Washed by means of the lubricant Wash from the nozzlesI6, I'I and I8. rihe bearings are continuously washed throughout theentire length of the washing machine II and are discharged at 23 at thefar end of the washing machine.

As best shown in Figure 2, the washing machine I I comprises a baseplate 24 mounted on longitudinally extending channel members 25 and 25which form a part of the supporting framework. L-shaped track members 2and 28 are spaced apart laterally on the bed plate 24 and are adapted tobe moved toward and away from each other by means of a turnbuckle screw29 having a threaded portion 30 engaging a threaded aperture 3| in adownwardly extending portion 32 of the track member 2'I. The turnbucklescrew has an oppositely threaded portion 33 threadedly engaging anaperture 34 in a downward extension 35 of the spaced apart track 28. Thethreads are so arranged that upon rotation of the turnbuckle 29 thetracks 2l and 28 are carried inwardly toward each other or away fromeach other depending upon the direction of rotation of the screw 29.Vertically extending u bracket members 36 and 37 at the extreme sides ofthe washing machine Il and extending upwardly from the base plate 24journally support the turnbuckle screw 29. A bevel gear 38 is xedlymounted on one end of the shaft 2S and is operatively engaged with asecond bevel gear 39 mounted on a shaft 40 bymeans o f a key 4I. It willthusbe apparent that rotation f the'shaft 40 will cause the adjustablepositioning of the spaced apart bearing tracks 27 and 28. An end thrustwasher 42 is mounted ontheother endet the turnbuckle shaft 29 by meansof a p in 43 insuring that the turnbuckle s'rewremain lin fixed lateralposition with "respect to fthe base plate 24. 'Y

As best shown in Figures 2 and'4, "the bearings 22 to be washed areslidably fmountedx-cn the track members 27 and 28. The ttings` l5, I]and I8 are associated with a longitudinally 'e'xtending nozzle 44 havinga plurality of slits 45 'which l'are vadapted -to be l'directed upon`the bearings 22 as they pass along the track members '237 fand '528.Duplicate 'conduit Yfittings 3l 6', 197 and I8 are positioned directlyopposite the ttings 116', vIf'l and 118,' respectively, and are adaptedto feed the liquid washitcafsecondelongated nozfz'Ie 46 'which liesparallel to the nozzle44 and spaced therefrom.

Thesno'zzles44 and JV46` -h'ave 'their stream directing slits inclined in Such 'amanner that fthelinner races 48 thereof, alongjwith the balls 49,`-'a`rerotated'with-respect :to 'the outer 'race 5e `vwhich is heldsubstantially a'gan'st 'r'otation by the frfricti'rial engagement -withthe track members 127 land l28 and also the frictinal engagementcausedfby thefabutting of 'the 'ball bearings With each other during thefeeding of the bearings along the longitudinally extending track. Thenozzle 944, 'as viewedin YFigure 1, has the -slits "4E-inclined at anangle Vfrom a. high portion 'at-the feeding end of the wash-ing Emachineto a low discharge pcrtio'n vat vthe discharge endv of jthe vwashingmachine. 4Iflxfe slits 45 are so directed lfr approximately ionehalf thelength 'of-the washing rmachine'aside-- -finedby Vthe conduit *'l'4Yandffitti'n'g H. There- "after, for th'errem'ainin'gVextentlof thewashing -machinef or approximately theil'ast halfither'ecf, the slots in'thefnozzle `'44 iare fdesignated by the 'numeral 45' land arefinclinedin Sa direction op- ='pos'ite to Tth'at'ofthe slots 45. Thefslots 45have their fhigh .pointat 'the discharge end "of 'the washing 'machine:and 'vare inclined downwardly in a direction toward the fee'olin-'gl"end offth'e Washingfmachine. As best shown in Figure 4, the slots-47in the nozzle 45 refer to the *slots-lin that half` of the washingmachine nearest the `feeding end thereof, and the slots 'or slits 47'refer. to those positioned in the last half of the nozzlelllor that halfadjacent thedis'charge end of the washing machine. The slitsr4-7Pare'1inclinedpposite to'th'atfofithe slit's'll and hence aresimilar in inclina-tion to fthelslits 45 wherethe high 'portion lisadjacent theldischarge`end of 'the washing machine 'andltliere-iiponisinclined downwardly tdwar'd the 'feeding "end of ythe washing machine.'In'tlie' same' manner that the slitsf are inclined opposite' withrespectfto `the slits 45, the slits '4-7lare inclined-ina directionopposite to the inclinationof-theslit's fll'l-an'd--as-'a result areinclined in thersame'dir'ection as the slits 45 inwhichthe'highfportionsthereof 'are adjacent the `feeding end -ofthe'washing ma# chine and thereupon are inclined downwardly toward thedischarge end of the washing machine. As the bearings 22 are moved alongthe tracks 27 and 28 by reason of succeeding bearings from the stack 2Qbeing inserted into the machine, the streams of wash liquid fed to theslits "45 and 47 enter or 'wihiinge againstlthe surface of the bearingsin such a manner =that the slits 47 tend to drive the inner race andballs 43 I"and 49 respectively in a direction as indicated by thearrpwl, whereas the stream passing through the'incline'd slits 45 tend torotate the movable fbeafring fparts nadirection as indicated by thearrow/*5552, with thefnet result that the inner porti''n's ofthe bearingare rotated in a counterclockwise 'directin as viewed in Figure 4 andindi'cated fby the varrows 53. The liquid wash thoroughly soaks thebearings 22 and stirs up and removes any grit or filings that may be,lodged on the critical polished bearing surfaces. yI-he in'o'vihg'ipa'rt's bf2-the "bearings are lrstfrotated in a counter-'elockwise-direction throughiyo'iit the entireliirst lhalf 'of the washingmachine, Aand :immediately upon the bearings passingthe central dividingline, the oppositelyiinclinedslits -45 and f4.7' reverse 4the Ydirectionof rotation of 'the Sinner -races 48- 'and ball's v'49.

The members262 and Micarryingthe'lipmem- *bers l4` and F65 aremvableilaterall'y.aswell as "verticallyiniordertolbeiproperlypositionedf'with ed respect to the openings 45 and 41. Arectangular frame composed of parts 66 and 61 extends around the bearingholding track. The portion 66 is welded to the track member 21 at 68 andthe portion 61 is attached to and movable with the track member 28. Itwill thus be seen that as the rightand left-handed screw 29 is rotatedby means of the bevel gears the frame members 66 and 61 are laterallyshifted simultaneously with the shifting of the track members 21 and 28.'Ihe frame portion 66 is provided with an end across member 69. A iirstupright member is bolted at 1| to the end across member 69 and thus alsois laterally shiftable with the track member 21 and the frame portion66. The opposite side of the device, that is, the frame portion 61, issimilarly constructed with an upright member 12 which performs theidentical function to that of the member 10. An extension 13 in the formof a fork carries spaced rollers 14 and 15. The first upright member 10projects between the rollers 14 and 15 thus providing a source of movingpower to effect lateral shifting of the member 62. The rollers reducethe amount of friction thus making for easy movement of the valvesliding member 62. The slide valve member 63 is similarly provided witha pair of spaced rollers 16 and 11 for reception of the upright member12. It will thus be evident that the slide members 62 and 63 aresimultaneously laterally shiftable in opposite directions.

The nozzles 44 and 46 are in the form of relatively long rectangunlarhousings having bottom portions 18 and 19 adjacent the inclined openings45 and 41. The slide members 62 and 63 are held to the bottoms 18 and 19by means of gibs 80 and 8| positioned at opposite ends of the respectiveslides 62 and 63. The slide members 62 and 63 are thus precluded fromseparate vertical movement with respect to the nozzles 44 and v46 butare permitted relative lateral movement with respect to each other forthe purpose of controlling the opening of the slots 45 and 41.

The nozzle 46 is equipped with an upwardly extending portion 82 whichhas an inclined top 83 and spaced roller members 84 and 85. An inclinedtrack 86 in the supporting structure I0 extends from a relatively highpoint on the outside of the machine to a lower point substantiallycentrally of the machine. The rollers 84 and 85 are adapted to slidinglyengage the track 86, and thus by reason of the lateral shifting of thenozzle 46 the entire nozzle moves in a path similar to the inclinedtrack 86. The nozzle 46 thus has both lateral and vertical movement withrespect to the base plate 24 and thus also the supporting structure I0.

The nozzle 46 is further provided with a lateral extension 81 as bestshown in Fig. "I. This extension 81 has a slot 88 inclined across thesurface thereof and adapted to receive and guide a roller 89 carried bya second upright member 90 attached to the frame or yoke 66 in a planespaced from the first upright member 10. The roller and slot engagementis further shown in Fig. 13 and it is thus apparent that rotation of therightand left-hand thread screw 29 will cause a lateral shifting of thenozzle 46 by reason of the roller 89 engaging the walls of the extension81. The upright member 90 is angled at the top thereof as shown at 9|.The inclination of the portion 9| is slightly different from that of theinclination of the slot 88, and thus lateral shifting of the member 90causes less lateral movement of the nozzle 46 than if the member 9| andcooperative slot 88 were both vertically disposed. Fig. 6

6.. shows the relative positioning of the upright members 10 and 90. Theroller 89 is formed in two parts 89a and 89h, which are positioned onopposite ends of the member 99, and the lateral extension 81 of thenozzle 46 is similarly provided with spaced portions indicated by thenumerals 81a and 81b within which the rollers 89a and 89b slide. Thenozzle 44 is equipped with similar moving devices and they will not beassigned further reference characters for the reason that the drawingswould be unduly cluttered with a plurality of numbers. The position ofthe nozzle 46 with respect to the large bearing 22, as shown in Fig. 2,is such that the opening 41 is fully uncovered by means of the slidevalve member 62 and the nozzle is spaced considerably above the bearingholding track member 21 to give ample space to the relatively deepbearing 22.

As shown in Fig. 3, the valve member 62 has substantially closed theinclined opening 41 for directing the impinging stream on the smallbearing 60. Further, the nozzle 46 has moved downwardly to a positionrelatively close to the track member 21, and the track member 21 hasmoved laterally inwardly to properly support this small bearing. Therelative movement of the slide member 62 with respect to the nozzle 46is accomplished by the direct and full movement of the slide member 62by the vertically disposed member 10 and the relatively slow lateralmovement of the nozzle 46 by the inclined slot 88 and its cooperativerollers 89. Thedevice is thus arranged and constructed so that a simplerotational movement of the shaft 40 will accomlish a proper adjustmentfor bearings of all sizes. It is believed that Fig. 9 best shows thepassing of the bearings to be washed through the washing machine of thisinvention. The bearings are in single file and mounted on the tracks 21and 28 as previously described. The feeding mechanism is very importantto the successful operation of this washing machine, and thus it isbelieved necessary to specifically show and describe the operatingelements of this feeding mechanism. The feeding mechanism 2| consists ofa carrying structure 92. The carrying structure 92 extends beneath themagazine I9 and thus also beneath the vertical column of bearings 20 tobe washed. A vertically movable table or the like 93 is adapted incertain instances to support the vertical column of bearings 20. Themember 93 has a downwardly extending shaft or piston member 94 journallymounted in the carrying structure 92 the lower end of which is adaptedto be engaged by a cam member 96. The cam member 96 is mounted forrotation on a shaft 91 supported by bearing brackets 98 depending fromthe carrying structure 92. The feeding mechanism thus depends for itsactivity upon rotation of the shaft 91 and thus the cam 96 whichcontrols the cycle'of operations of the feeding mechanism elements. Anarm |03 is mounted on the shaft 91 for simultaneous rotation therewith.

A connecting link |04 joins the outer end of the arm |03 at |05 and atits other end is connected at |06 to a downwardly depending arm |01. Thedepending arm |01 is attached to the under side of a laterally slidingmember |08 which is mounted for sliding movement. The slide member |08has mounted thereon a block member carrying a vertical shank member ||2of a forwardly extending fork-like member I I3. The shank member I2 isadjustably locked in the block III by means of vertical adjusting 7 Itill :and a. horizentally fdisposed set :or lackingfscrew1 l-:Ia 4Ehefnrk Ll 3ds cumposedeof apluralityf spacedfngers H5;
